OBJECTIVE We assessed the value of combining (123)I-IMP brain perfusion SPECT and (123)I-MIBG myocardial scintigraphy for the discrimination of dementia with Lewy bodies (DLB) from other types of dementia. METHODS We subjected 252 consecutive patients with clinically suspected DLB to both (123)I-IMP brain perfusion SPECT and (123)I-MIBG myocardial scintigraphy. Patients with Parkinson's disea...

Myocardial bridges are congenital structural abnormalities with debated clinical relevance; they may be traditionally asymptomatic or associated with various clinical manifestations, some of which may be potentially fatal. We report on a 60 years old man, who underwent a follow-up stress/rest myocardial perfusion scintigraphy developing asymptomatic exercise-induced ST-elevation and demonstrati...

A 74-year-old man was referred to the Cardiology clinic with a 3-week history of exertional chest tightness. These episodes lasted a few seconds without any limitation to activity. The gentleman is an ex-smoker and a hypertensive on treatment. The results of the clinical examination and ECG were unremarkable. An exercise tolerance test was found to be negative, albeit at a subtarget heart rate....

We have devised a new position (Monzen position) which can suppress the influence of scattered rays from surrounding organs (liver, etc.) when conducting myocardial imaging. Unlike the conventional techniques, which require a waiting period of 30-60 minutes before imaging can be started after the infusion of technetium-99m sestamibi or technetium-99m tetrofosmin, this position allows single-pho...

This study addresses the question of communication between medical wards and the nuclear medicine department for the realization of myocardial perfusion scintigraphy. It analyses the effects of a reminder for completing the content of an order form. It shows that the CDSS impacted ordering practices. It could be seen as a system enabling to structure the information and improve the quality of o...

Experimental work has shown that even small reductions in myocardial perfusion impair contractile performance. We, therefore, studied the relationship between regional perfusion, assessed by thallium-201 scintigraphy and segmental wall motion, quantitated on biplane contrast ventriculograms, in patients with coronary artery disease. We evaluated 270 segments in 54 patients, including 27 without...

OBJECTIVE To assess the prognostic value of Technetium-99m-labeled single-photon emission computerized tomography (SPECT) in the follow-up of patients who had undergone their first myocardial revascularization. METHODS We carried out a retrospective study of 280 revascularized patients undergoing myocardial scintigraphy under stress (exercise or pharmacological stress with dipyridamole) and a...

transient ischemic left ventricular dilation (tid) is a marker of severe and extensive coronary artery disease as well as an increased risk of adverse outcomes. the patients with more severe and extensive ischemia, multivessel-type of perfusion abnormality as well as patients with left anterior descending artery (lad) territory perfusion abnormality have more probability of having tid. evaluati...

according to the importance of positron emitters in nuclear medicine, 82mrb was produced as a member of this group of radiopharmaceuticals. after being converted into an injectable form, enough information was provided for imaging with this radiopharmaceutical. 82mrb with high radioisotopic purity and half-life of 6.5 hours, in chloride form, can be considered as a suitable positron emitter for...

background: cardiac risk assessment with myocardial perfusion imaging (mpi) is a common practice for some elderly breast cancer patients who are candidates for operation. in rare cases the tumor may become visible in the images. case presentation: this is the report of a case with a huge slow-growing breast tumor suspicious for malignancy and presenting with methoxy-isobutyl-isonitrile (mibi) u...
